That's a fairly solid argument, and, in different circumstances, you may be correct.
However, that kind of thinking only works on the very short term (less than 10 or so generations). Long term, you get what we have now with industrial monocropping, chemical fertilization, and exceedingly highly processed foods endangering the *entire* food supply chain, from soil to poop. Centralization always leads to failure, long term. Always. We are already seeing the limit of the system in place now. It will likely come crashing down in our lifetime.
